We're dividing 83697741 by 156 
The aim is to understand the frequency of 156 in 83697741.

Step 1:
If we divide 8 by 156, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 156

Step 2:
156 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (6) of the dividend behind the 83 and repeat the process: 836 / 156

Moving on to step 3:
If we divide 836 by 156, we get 5 and a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 780 from 836 to get 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 156

Moving on to step 4:
The number 156 fits into 569 3 times, leaving a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 468 from 569 to get 101.
Append the next digit (7) from the dividend to 101 and continue with: 1017 / 156

Moving on to step 5:
When dividing 1017 by 156, we get 6 with a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
Subtracting 936 from 1017 leaves us with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 156

Going ahead to step 6:
817 divided by 156 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 5365.0
If we subtract 780 from 817, we get 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 156

Moving on to step 7:
156 can be fit into 374 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 53652.0
The remainder is 62 after subtracting 312 from 374.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 156

Advancing to step 8:
621 divided by 156 is 3 with a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 536523.0
Deduct 468 from 621 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
If we divide 1530 by 156, we get 9 and a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 536523.9
Subtract 1404 from 1530 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
When dividing 1260 by 156, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 536523.98
If we take 1248 away from 1260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
156 can be fit into 120 0 times, resulting in a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 536523.98
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
156 goes into 1200 7 times with a remainder of 108.
Use 7 as the next digit of our solution. 
Result so far: 536523.9807
If we subtract 1092 from 1200, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
If we divide 1080 by 156, we get 6 and a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 536523.98076
Subtract 936 from 1080 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
If we divide 1440 by 156, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 536523.980769
If we take 1404 away from 1440, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
When dividing 360 by 156, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 536523.9807692
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 16:
The number 156 fits into 480 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 536523.98076923
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 536523.98076923 and a remainder of 1.2e-08.
